A1084-A/B Miniaturized GPS receiver
Positioning Products
for passive and active antennas
Many GPS applications, such as portable devices or telematics units, require
a built-in antenna. However, an external antenna connector is often desired for
GPS performance or reliability reasons. This is what the new A1084-A GPS
receiver supports with its second antenna pin and on board antenna switch,
whilst the A1084-B supports both passive and active antennas on a single
antenna pin. This very compact SiRFStar III based GPS receiver comes
completely shielded with a lid and with benchmark-setting GPS performance
on a very small footprint.
